Berlin - Germany's favourite polar bear, Knut, has celebrated his 4th birthday with a lavish party at his zoo attended by about 250 people.
Fish and meat were served in the polar bear's snow-covered, outdoor enclosure at the Berlin Zoo on Sunday, followed by a birthday cake shaped like the number four.
As Knut gobbled up his cake, the spectators sang Happy Birthday to him, the German news agency DAPD reported.
The visitors also were given the rare opportunity to feed Knut, and he seemed to enjoy the bread, fruit and fish they brought for him.
Knut has been a star in Germany since he was hand-raised by zoo keepers after his mother rejected him at birth. - Sapa-AP
